WARNING: If you are using "Pipe" test, you must verify that there is a
no flow condition before proceeding. If you are performing the test in a
bottle, be sure to isolate the sensor in a bottle - any air movement (even
from a fan) can result in a false "fail" result.
Once process is stable, press

NOTE: For best results:
1. Use the factory-supplied PVC sensor protector shipped with the meter
(see Fig. 2.1 on p. 67).
2.
Place the meter upside-down on a flat, solid surface before starting
the test.
3. Do not allow the meter to get jostled - make sure the meter is stable
and the sensor completely isolated.
